Linux system Why is the door popular?

What is the Linux system in your eyes? Today, the old boy made up to analyze the Linux system in my eyes?


Talk about Linux systems, unfamiliar and familiar. A few years ago, I have never heard of the word "system", not to mention Linux, it is a face, until the teacher talked about the Linux system, the heart has a little concept, only know that it is able to run the high-level "software" on the computer, real to deep learning, Just understand is a better than Windows operating system, and is open source, perhaps beginners mistakenly think open source is free, wrong! This can be said in turn (free is open source).

It is a free and open-source Unix-like operating system that anyone can freely use, completely free of any restrictions, so that 60% of the world's people are using it. Today, no matter where you are, it is impossible to use Linux, according to statistics, more than 2 billion people carry an Android phone every day to go out, its bottom is the Linux system, today's Linux system has been everywhere, contact more, slowly also familiar.

Linux is also widely used in embedded systems such as mobile phones, tablets, routers (Router), televisions and video games, The Android operating system, which is widely used on mobile devices, is built on top of the Linux kernel and offers many Linux distributions for desktop and server users to choose from.

"Investing in the Brain"-learning Linux can be a long process

When we know a series of advantages of Linux, there is no reason not to understand it, it is worth our deep learning, we need to explore the Linux world. Do not mind recommending a Linux tutorial reading "Linux should learn this", this is also a good book I recently read, this book can further improve the understanding of Linux systems, expand your horizons.

It is because of these reasons, let me like the Linux system, after reading, I hope you can also like Linux, like Open source.

"Hot" multi-user, multitasking, multi-threaded

Linux system can support multiple users at the same time, each user to their own file device has a special right to ensure that the user does not interfere with each other, like a mobile phone to open the same as the assistant, while landing multiple QQ account, when the hardware configuration is very high, each user can also perform multiple tasks simultaneously, multiple threads simultaneously work, Improve efficiency, is simply a perfect mess, only a multi-user to complete the explosion of other operating systems.

"Rock solid"-stability and efficiency

You may hear Windows server running for a long time and suddenly go down, but you will never hear Linux system servers get stuck for a long time, and this is almost not the case on Linux. Linux servers can run indefinitely without downtime because it inherits Unix's superior stability and efficiency. It is because of its stability to obtain the favor of many users, because it is efficient, it is more widely used, but Linux can also provide some high-reliability services, such as: LNMP, virtualization, database services and so on.

"Impregnable"-Security and SELinux

Its security is much more secure than other systems, because Linux has a large number of users and open source community support, so it can quickly identify system vulnerabilities, and quickly release security patches in time to update, but also has a strong "immunity" characteristics, rarely attacked by viruses, for an open system, In the convenience of users, there is likely to be a security risk.

However, the use of Linux with its own firewall (IPTABLES,FIREWALLD), intrusion detection and security certification tools, timely repair system vulnerabilities, can greatly improve the security of the Linux system, so that hackers can be inorganic, but also the security enhancement mechanism SELinux, The ability to provide mandatory access control in the Linux kernel is comprehensive enough to protect systems and services, but many people like to turn it off, which is not as good as the relative security.

There are also tcp_wrappers can provide a good network service access control, Linux system for user and file management Rights Management is also very good, can control permissions, ensure the confidentiality of files, but also other systems can not be compared, So the Linux system is, to some extent, indestructible.
